BUILDING U Application filed December 2,`1920`. Serial No 427,*750.

To all whom it may com-em:

Be it known that Lewis `W. TILTON, a

citizen of the United States, residing at,Mi-' ami', in the' County of Dade and State of" Florida, have invented certain new and useful lmprovements in a Building Form; and

I do hereby declare the `following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art 'to which the same.

The object of the invention is toprovidea simple, relatvely. ineXpensve and, e'flicent' filling unit toi' building forms :is a substitute for the wooden fillers ordinarily employed between the joist and girders concrete and similar work in connection with building Operations, and'more especially to provide a unit which can be used repeatedly and for an indefinite lengthof time and is adaptahle to the Varying joist spacing to be 'found in buildings and which are usually arranged on twelve inch, 'ourteen inch or sixteen inch centers according to the purposes for which the buildings are designed; and with this object in view the invention consists in a Construction and combination of parts of which a preferred embodiment is shown in the drawing, where Figure l is a plan view of a filler unit'embodying the invention arranged in the operative position with relation to the building timbers. i

Figure 2 is a detail View of the unit detached, and showing in dotted lines the adjusted position of the supporting brackct by which the same is adapted tor use in connection with joists spaced at the intermediate interval of. say, 'ourteen inches. 40

Figure P is a View similar to Figure l, illustrating` the manner in which the filler unit is used in connection with oists spz'ced at an intermediate interval. n

Figure 4 is a fragmentary plan view showing the invention in use.

The device consists essentially of metal plate 10, preferably sheet metal as steel' to which is atteched means 'for supporting the same in proper position with relation to the joists 11 or other timbers of the building structure, said means in the construotion illustrated consisting of angular brackets 12, one arm of which is Secured by bolts 13 to theplate 'while the other arm is provided with perforatons 13 through which nails 14 may be driven to attach the brackets to the it appertains to make andnse' v n between an outside form 17 andan nsde tering openings in the members and serving timbers ;such'as fiooring lgpermanent or' temporary, it being preferable to drive these nails; 'as shown, only a part of' theway 'and:`

then bend them'over so that they may readily' be withdrawn when the unit is 'tobedisplaced atthecompletion of the operation.

Figure. t best illustrates the use of; the plate 10. Aconcreteor equivalent wall is suggested at 16 having the end's of joists 11 extending into the same. his wall is poured :form 18 and it 'is customary to nail boards in the intervals between the joists 11, the .form 18 and the timbersl; The plate lOis ,used instead of said boards in' accordanee with my invention. As 'the joistsj ll'are variously spaced in accordance with 'building rules or Customs either at twelve, `tourteen or sixteen' inch centers,.the plate consists ofia n1ain"75 plate or body portion 10 having a width and a length adapted respectively for the inter Vals between joists spaced' at 'twelve and v fourteen inches between Centers and an eX- tension 10 serving to add to the width of the plate to adapt it to fill the interval between joists spaced atsixteen inch Centers. The extension member is secured to the body member by means of bolts 13 engagng registo permit of the detachment of the extension with facility when the devioe is to be used in connection with joists spaced at twelve inch Centers. To Convert the unit arranged for use either in connection with joists spaced at twelve or sixteen inch centers, to adapt it to be used in connection with joists spaced at fourteen inch centers or at the inte'rmediate dimension, it is only necessary to shitt the supporting bracket trom the side edge to the end edge ot the body member of the plate, to use the supplemental bolt holes 14:

- such adjustment or rearrangenent being indicated in dotted lines in Figure 2, and obviously being' such as can be effected by cheap labor and without neccssitating e pert or skilled workmen. i\ i Thus by providing a plate of which the body portion is of ohlong form adapting its width and length respectively to the intervale represented by different spacings of the building joists or timbersand providing the plate with an extension in one directionit is possible to adapt the plate to' the several spacings of joists and other like floor timbers as'they are ordinarily arranged or as they are universally arranged in connection with the customary rules of building Construction. The inte'rohangeabiiity of the supporting means to adapt the same to either the side or end edges of the body member of the plate, or other perpendicularly disposed edges thereof, the said body member of the oblong form indieated, enables the unit to be properly supported during the operation of plaoing the eoncrete or cement and at the same time faoilitate 'the removal thereof after the oompletion of the operation. 'To hold the bottom the unit should be dropped from the inside of the girders so that the braeket will rest on the sub-floor over the girders whereupon nails may be driven in the openings or perforations in the perpendioularly disposed braoket arms to hold the deviee in place. The opening 16 at the center of the plate is provided tor a wire to be used in connection with *foundatiors when the same are poured.

Having thus described the invention, what I claim sz 1. A fiiler unit for building forms having a plate of greater length than width, an extension attachable to the plate to increase the width thereoi whereby the unit may be used between joists spaced at different distanoes apart.

2. A filler unit for building forms having a plate of greater length than width and means to seleotively support the plate with a side or end uppermost whereby the unit may be used between oists' spaced at different distances apart.

3. A filler unit for building forms having a plate, and supporting means 'or interchangeable connection adjacent to one edge of said plate and adjaoent to another edge of said plate at an angle to the first mentioned edge.

4. A filler unit for bulding forms having an oblong plate, angular supporting brackets and bolts for securing the plate to said brackets, said plate being provided with bolt openings in operative relation with 'perpelidicularly disposed edges thereof.

5. A filler unit for building forms having a plate oonsisting of a body member and e detachable extension member, said body member being of oblong form, supporting braokets and means for attaching the supporting braokets to' the body member of the plate and adapted for interehangeably arranging the braekets adjaeent to a side or end edge of said body member.

In testimony whereof I affiX my signature in presence of two witnesses.

LEWIS W. TILTON.
